Each week mrs endo bikes 0.86 mile to the garden. Then she bikes 2.3 miles along the river back home. About how many miles will mrs endo bike in a year?

164.32 miles

Step-by-step explanation:

Given that:

Weekly coverage :

Miles biked to the river = 0.86 miles

Miles biked along the river back home =. 2.3 miles

Total miles biked weekly:

(0.86 + 2.3) miles = 3.16 miles weekly

Number of weeks per year = 52

Miles biked yearly : (number of weeks per year * miles biked weekly)

= 52 * 3.16 miles

= 164.32 miles

Mrs endo will bike about 164.32 miles in a year.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
